Donner Octave Pitch Guitar Pedal Harmonic Square First Look Review

Donner Digital Octave Guitar Effect Pedal Harmonic Square 7 modes

Donner has proven to be a quality company in the guitar pedal market over the last few years. I own about 30 of their guitar pedals, 5 of their ukulele’s, and some of their other music related products.

Today we’ll have a look at the Donner Harmonic Square mini guitar pedal. You can get a lot of cool sounds from this pedal. Beef up your single note riffs and solos, get a 12 string kind of sound, a bass sound, and many other kinds of tones. You get 7 modes, +2, +3, +4, +5, +6, 1 octave, and 2 octaves. Each mode can be tuned up, tuned down or detuned, so it’s more like 21 modes plus a wet and dry mix to even things out. I tried this with a 12 string electric as well (not in a video) and got even more cool sounds. Overall, I Love this pedal and would recommend it. Check out the video to hear some sounds.
